Dating to 1970, this fabulous piece features a sparkling round brilliant-cut diamond at the centre, surrounded by six oval opals interspersed with a further six round brilliant-cut diamonds to create a striking hexagonal cluster. The opals display a wonderful play of colour, with flashes of green, blue, yellow and orange shimmering beautifully as they catch the light, while the diamonds add lovely sparkle throughout. With a cluster measuring approximately 15mm in diameter, this is a wonderfully eye-catching statement ring for lovers of opals, diamonds and retro jewellery.\u003cspan aria-hidden=\"true\" class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"1165\" data-end=\"1515\"\u003eDetails:\u003cbr\u003e• Metal: 18ct yellow gold\u003cbr\u003e• Gemstones: Opal; diamond\u003cbr\u003e• Style: Cluster ring\u003cbr\u003e• Cluster size: Approx. 15mm diameter\u003cbr\u003e• Size: UK size O 1\/2 (US size 7 1\/2)\u003cbr\u003e• Weight: Approx. 3.9 grams\u003cbr\u003e• Hallmarks: London Assay Office\u003cbr\u003e• Maker's Mark: FO\u003cbr\u003e• Era: 1970s (date letter for 1970)\u003cbr\u003e• Condition: Very good\u003c\/p\u003e\n\u003cp data-start=\"1517\" data-end=\"1681\"\u003eA complimentary ring box will be provided, ensuring this beautiful opal and diamond ring arrives ready for gifting or as a fabulous addition to your own collection.\u003c\/p\u003e","brand":"Second Sparkle","offers":[{"title":"Default Title","offer_id":58120895987976,"sku":"2126","price":575.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/2308\/6344\/files\/DSC_0495_736cd7c7-bcf1-4806-9f0a-26f80ee36a9d.jpg?v=1783006423","url":"https:\/\/secondsparkle.co.uk\/products\/opal-diamond-ring-5","provider":"Second Sparkle","version":"1.0","type":"link"}
